Dart and Dart Game

Abstract

A recreational throwing dart comprising a target area at the rear capable of capturing the tip of another dart thrown into it while the dart is in the dartboard and a game comprising said dart. The dart is thrown into the dartboard and then a second dart is thrown at the target area of the first dart in the dartboard. The point of the second dart can stick into, be mechanically captured by, or otherwise adhere to the rear portion of the first dart. This dart creates a new form of gameplay different from traditional dart rules in which the tip of all darts must strike and stick into the dartboard itself. The invention allows the darts to not be damaged by the second dart sticking into the rear of it as happens when a standard dart pierces a dart flight or a dart shaft.

DETAILED DESCRIPTION OF THE INVENTION

[0080] FIGS. 1-4 are various views showing a first embodiment of the apparatus of the present invention designated generally by the numeral 10. Dart or gamepiece 10 preferably comprises a flight 11, a shaft 12, a barrel or grip 13, a tip or point 14, and a target / target area / receiving area 15. The target / receiving area 15 is preferably located within a cavity / recessed portion 17 of the rear end or area 16 of shaft 12 (when the shaft 12 and flight section 11 are part of a single structure as shown). Alternatively, target/receiving area 15 can be in a cavity located centrally of the flight fins 18 in other embodiments in which the flight is separate from the shaft 12. Although target 15 is shown recessed in the cavity 17 of the rear end 16 of shaft 12, the target need not be recessed. The target can be flush with the outermost portion of the cavity 17, the target can extend past the outermost portion of cavity 17, or the target can be partially recessed (as shown in FIGS. 2 and 4, for example). FIG. 1 is a rear view of dart 10, showing the target 15 in the center area of the rear end 16 of shaft 12. Target 15 allows another dart 10 to stick to / adhere to / be captured by an initial dart by receiving the other dart’s tip or point 14. Target 15 in the rear of the dart 10 thus enables another dart 10 to stick into the rear of the dart 10.

[0081] FIG. 4 is a perspective view showing one dart 10 of the first embodiment striking another dart 10 of the first embodiment in the target area 15 by the dart’s point or tip 14. As can be seen in FIG. 4, a dart 10 that strikes another dart 10 in its target area 15 can cause the two darts 10 to be stuck together. Furthermore, the target area 15 of the second dart 10 is available for another dart, for example, a third dart, to strike same, adhering three darts together.

[0082] FIGS. 5-6 show a second embodiment of the present invention designated generally by numeral 110. Flight unit with threaded shaft 110 preferably comprises flight 11, shaft 112, shaft rear end 116, cavity 17, target 15, and threaded end 120. The second embodiment is similar to the first embodiment shown in FIGS. 1-4. Flight unit with threaded shaft 110 lacks the barrel or grip 13 of dart 10 as well as the point or tip 14 of dart 10. Flight unit with threaded shaft 110 has a threaded end 120 of shaft 112 which allows it to attach, for example by screwing onto, a barrel and tip attachment. Thus, flight unit with threaded shaft 110 can be attached to existing dart parts to create a dart similar to the dart of the first embodiment.

[0083] FIGS. 7-8 show a third embodiment of the apparatus of the present invention designated generally by numeral 210. Flight unit / flight attachment 210 preferably comprises flight 11, rear shaft portion 216, cavity 17, target 15, and shaft attachment 230. Shaft attachment 230 of flight unit 210 is preferably sized and shaped to allow attachment of flight unit 210 to a shaft of a dart so as to modify a normal dart into one with a rear target area as set forth in the present invention. In other embodiments, the flight attachment 230 is sized the same as a standard flight (the fins 18 connect at a central axis and there is no body, similar to the embodiment shown in FIGS. 9-12, for example; there is no body, such as cylindrical body 231 that is centrally located of the forward end of the fins).

[0084] FIGS. 9-12 show a fourth embodiment of the present invention designated generally by the numeral 310. Flight unit / flight attachment 310 is similar to flight unit 210. However, flight unit 310 comprises two or more folding fins 340, 341 of flight 311 and two or fewer non-folding fins 342, 343. That is, dart attachment 310 could have two, three, or four folding fins and two, one, or zero non-folding fins, respectively. In the drawings shown, only two folding fins, 340, 341, are shown. The folding fins 340, 341 allow for easier storage and shipment of flight unit 310. As shown by arrow 350, fin 341 can move toward fin 342 for storage (while fin 340 can move toward fin 343). Flight unit 310 also preferably comprises a target 315 which can be generally square in shape and not recessed like the target shown in FIGS. 1-8. Target 315 is preferably located within flight unit rear portion 360, which may be shaped as a square pyramid as depicted in FIGS. 9-12. The target in each of the various embodiments can take the form of various shapes and materials and can, but need not be, recessed in each of the various embodiments. The other embodiments described herein and shown in the figures can, but need not have, folding fins as well. In each of the other embodiments, each flight preferably comprises multiple fins, as depicted in the figures. The flights are also not limited to four fins as is shown in the figures.

[0085] FIGS. 13-15 show a fifth embodiment of the apparatus of the present invention designated generally by the numeral 410. Flight unit / dart attachment 410 preferably comprises flight unit 411, a flight unit rear portion 460 that is generally cylindrically shaped and corresponding target area 415. In this fifth embodiment, similar to the fourth embodiment 310, flight unit rear portion 460 which preferably houses the corresponding target 415 is preferably integrated into the flight component 411 rather than a part of the shaft of the overall dart (not pictured). In this way, flight units 310 and 410 can be directly attached to a dart of the prior art, converting said dart into a dart capable of receiving the point or tip of a dart and allowing for modified game play, as described herein.

[0086] FIG. 16 depicts a rear view of a sixth embodiment of the apparatus of the present invention designated generally by the numeral 510. Flight unit 510 preferably comprises flight segment 511, flight unit rear portion 560, and target area 515 which preferably comprises multiple channels or receiving areas 570-576 for capturing the tip of a subsequently thrown dart. Although target area 515 comprises seven holes in FIG. 16, the target area 515 is not limited to or restricted to seven holes. This embodiment demonstrates that the rear target area need not be uniform. In game play, different values can be given depending on which of the smaller targets / channels 570-576 the subsequently thrown dart sticks to. Each of the multiple holes or receiving areas can be filled with foam, rubber, sisal, cork, or any other material that will allow a subsequently thrown dart to enter the hole and not bounce out. Alternatively, receiving areas 570-576 can be hollow, thus relying on the dart inserting far enough into the hole / tube so that it rests in position. Although the channels 570-576 are shown as equally sized and shaped, the shape and size can vary. The channels 570-576 need not be uniform in shape and size.

[0087] FIG. 17 shows a seventh embodiment of the apparatus of the present invention designated generally by numeral 610. Flight unit 610 preferably comprises flight unit rear portion 660 which is preferably shaped so that the tapered portion 613 of a barrel / grip and point or tip 614 fit into flight unit rear portion 660 at target area 615. Flight 611 is preferably shaped so as to allow for integration of flight unit rear portion 660. Although rear portion 660 is shown as a cylindrical pyramid 661 with a narrower extension portion 662, rear portion 660 can be of any shape which matches or mimics tapered portion 613 of barrel / grip 616 and point 614.

[0088] FIGS. 18-19 show an eighth embodiment of the apparatus of the present invention designated generally by numeral 710. In this eighth embodiment, rather than have the target area nestled within the dart flight, that is, not having the dart flight extend substantially past the dart flight rearwardly, in this embodiment, the target is preferably attached to the flight (or created as a unitary piece with the flight), and in this embodiment the target portion preferably begins distally of the rearmost flight fin. Target attachment 710 preferably comprises a target area 715 and body 716 which can be attached to the rear of a dart. As shown in FIGS. 18 and 19, target attachment 710 can attach to an existing dart flight component 711. In various embodiments, this rear target 716 can be removably attached to the flight 711. In this way, the size and shape of the rear target 716 can be changed, for example, during game play.

[0089] FIGS. 20-22 show parts that make up a ninth embodiment of the apparatus of the present invention, designated generally by the numeral 810. Dart 810 comprises flight component 811, shaft or body 812, barrel / grip 813 and point / tip 814. Referring to the dart point 814 as the proximal end of the dart and the flight 811 as the distal end, the dart flight 811 comprises proximal end 822, distal end 820, and cavity or receiving component 821. Flight 811 has four fins 825 but can have fewer or more in other embodiments. Cavity 821 is sized and shaped so as to receive target insert 816 (see FIG. 21 for target insert 816). Target insert 816 preferably has a proximal end 817 and a distal end 818. At the distal end 818 of target insert body 819 is lip portion 823 has a diameter greater than proximal portion 824 of target insert 816. Target 815 preferably fills the bore of target insert 816 and can comprise any of the materials listed herein for the flight targets. When target insert 816 is inserted into cavity 821 of flight 811, lip portion 823 and target area 815 are preferably exposed rearwardly from the dart. Lip 823 is designed to prevent damage to the rear of the dart assembly and serves to deflect the tip of the second dart in or out of target area 815. Lip 823 also provides a surface for a user to grip onto to remove the cup / cork / target insert 816 from the rear of the dart assembly 810. Although flight 811 and shaft 812 are a unitary structure in this embodiment shown, they need not be. Flight target insert 816 can be replaced if, for example, during gameplay it is damaged. Additionally, the width of the lip portion 823 can vary - the greater the width of the lip portion 823 the smaller the target area 815. As seen in FIG. 22, the proximal end of shaft 812 can have an end / connector / protrusion 826 which can be attached to barrel / grips of darts of the prior art. In this way, the present invention can be sold as a unitary structure, as individual pieces which are put together to form an entire dart, or as individual parts which are added to existing dart pieces to from a dart of the present invention.

[0090] FIGS. 23-25 show the components that can make up a tenth embodiment of the apparatus of the present invention, designated generally by the numeral 910. The embodiment shown in FIGS. 23-25 is preferably similar to the embodiment shown in FIGS. 20-22 except that the size (diameter) of the cavity 911 is decreased and thus, correspondingly, the size of the target insert 916 and target area 915 have decreased. However, as the target area decreases, the area of each fin 925 increases (compare fins 825 with fins 925). The size of the fins can vary and need not be directly tied to whether or not the target area is increasing or decreasing. It is possible to have an embodiment where the target is smaller than what is shown in dart 910, and yet, the fins 925 correspondingly are smaller as well. Or the converse can happen: the fins can become even larger as the target area decreases. The dimensions and size relationships between parts that are shown in the figures are not meant to be limiting. FIG. 25 is similar to FIG. 22 in that it shows end / connector / protrusion 926 which functions in a similar manner to end / connector / protrusion 826 of the ninth embodiment.

[0091] FIGS. 26 and 27 show eleventh and twelfth embodiments of the apparatus of the present invention, designated generally by the numerals 1010 and 1110, respectively. Darts 1010 and 1110 are preferably similar to the ninth and tenth embodiments. However, the target area / target portions 1015 and 1115 are not part of a larger target insert as seen in the ninth and tenth embodiments. Instead, the cavity portions are filled directly with the targets 1015, 1115. In this way, without the insert and corresponding lip, the target area is comparatively bigger than in the embodiments shown in FIGS. 20-25 (assuming cavities of the same diameter). In the eleventh and twelfth embodiments, the flight sections are shown by numerals 1011 and 1111, respectively.

[0092] The present invention also discloses a modified darts game. In the present invention, a first dart can be thrown into the dart board and a second dart can be thrown and can stick into/engage with the rear target area of the first dart. Because of the target area component of the first dart, the second dart can pierce and stick to the target area of the first dart. In standard dart designs, that would cause damage to the rear of the first dart. During gameplay, it would also result in no score in traditional dart rules.

[0093] The present invention allows for an added dimension of gameplay along with a non-fixed target location. The dart target area / capture area can be part of the flight, part of the flight unit, part of the dart shaft or an additional attachment that attaches to a dart flight or shaft. The new dart enhancement can be produced as flights for existing darts, flights with shafts attached, shafts, flight attachments, rear dart attachments, or full one-piece darts, for example. The rear of the new dart can have a circular, square, or other shape target for a dart to land in. The dart target/capture area can be made of metal, plastic, wood, vinyl, graphite or another light or suitable material, and then filled with a cork, sisal, foam, or other suitable material that can capture the tip of another dart and not have the subsequently thrown dart bounce out. Another embodiment could have the target/capture area be a mechanical device that would capture the tip of the other dart or be shaped like a spring or Chinese finger trap to capture the tip of the second dart. In various embodiments, the present invention may comprise a flat folding flight (i.e. nylon) that has a target area (which may be cone shaped, for example) in the middle to capture the tip of the other dart simply by shape. In various embodiments, there could be a version that is only single use or has an attachment target area that is single use such as a cover over the target / capture area or a piece of foam that can only be used once and then needs to be replaced. The front tip and grip area of the dart can be modified to promote the docking of the tip of the dart into the receptive area at the back of the dart. This can be done by shaping the tip and grip to fit into the rear of the dart. The dart target/capture area can be made of metal, plastic, wood, vinyl, graphite or another light material, for example, and then filled with a cork, sisal, foam, or other material, for example that can capture the tip of another dart and not have it bounce out. Another embodiment could have the target/capture area be mechanical device that would capture the tip of the other dart or shaped like a spring or Chinese finger trap to capture the tip of the second dart. Alternatively, or in addition, the various embodiments could use a material such as rubber on the grip to reduce bounce and increase friction with the docking area at the rear of the dart. The front of the grip portion or barrel can be in a pointed / cone shape to allow easier entry into the target/capture area.

[0094] The present invention can also apply to and include soft tip darts. For soft tip darts, the rear of a dart may have an area for another dart to hit which can then drive the first dart into the board for electronic scoring as opposed to having the second dart stick into the first dart as is done with traditional darts and in the embodiments depicted in the figures. Alternatively, however, the soft tip dart can be captured in a way similar to the capture of a steel tip dart.

[0095] In various embodiments, the sharp tip/spike of the dart can be stored in the target area of the rear portion of the dart. Such a feature could be advantageous for carrying and storing the darts.

[0096] The new dart and dart parts of the present invention allow several additional gameplay options, including modified scoring of traditional dart games, modified game play of traditional dart games, and entirely new game play. Some of the new options are listed below: [0097] When a dart is thrown into the target section of a dart already in the dart board, then the scoring could be: [0098] 1. The same number of points as the dart it is stuck into. [0099] 2. Double the score of the dart it is stuck into. [0100] 3. A fixed number of points such as 20, 50, 100, etc. [0101] If a dart is thrown into the target section of a dart already stuck into a dart that is stuck in the board then the scoring could be: [0102] 1. Triple the score of the dart in the board. [0103] 2. A fixed number of points such as 100, 150, etc. [0104] If a player’s dart is thrown into the target section of another player’s dart already stuck into the dartboard: [0105] 1. The player with the dart in the board loses their points for that dart. [0106] 2. The player with the dart in the board loses their dart for the remainder of the game. [0107] 3. The player that throws their dart into the target area of the other player’s dart gets additional scoring such as those listed above.

[0108] Other variants of the game can include players alternating turns or dart throws as described below:

[0109] In a particular method of gameplay of the present invention, each player throws three (3) darts and then removes them from the board. The first way to play is a take on the normal gameplay of darts where each player throws their darts and then removes them from the board at the end of their turn. The first dart thrown into the board scores the number of points on that section of the board as normal. If the second or any subsequently thrown dart sticks into the first or any previously thrown dart then the second or subsequently thrown dart can be worth the same number of points or another factor, such as double the number of points, of the first or previously thrown dart. It can also be its own point value such as 50 anytime a dart goes into the back of another dart. Similarly, if the third dart is thrown into the back of the second dart which is in the back of the first dart that could be worth the same or a different amount, such as triple the score of the first dart, or 150 points, or the same points as the first dart.

[0110] In another method of gameplay of the present invention, each player throws three (3) darts and leaves them for the next player. In this mode of play, the first player will throw their three (3) darts into the board, getting the score based on the normal dart scoring pattern. The second player will get points by throwing their dart into the board, or by throwing their dart in the back of the other player’s dart. If that happens, the first player can lose their dart for the rest of the match, lose their points for that dart, or the second player could get the score of that previous dart.

[0111] In an alternative, simpler game embodiment of the present invention, the second player is the only one who can score and only by sticking a dart in the back of their opponent’s dar, which could be worth a point, for example.

[0112] In another method of gameplay of the present invention, “Knockout,” an attrition/killer/knockout game, wherein when the second player gets their dart in the opponent’s dart, the opponent loses that dart for the rest of the game until one player has no darts left.

[0113] In another method of gameplay of the present invention, each player throws one dart, with each person alternating shots until all darts are thrown. In this mode of gameplay, players alternate their shots, and the same rules as above can apply when a dart is “robinhooded”; however the gameplay is slower.

[0114] In another method of game play, a first player throws the target dart, and then normal darts are thrown afterwards. In this gameplay, there are target darts thrown before regular darts. The target dart or darts are thrown into the board, and then the players try to throw a normal dart into the target section of the target darts.
